react-doctor/no-uncontrolled-input

Pass an explicit initial value to `useState` (e.g. `useState("")` instead of `useState()`), add `onChange` (or `readOnly` to opt out) when you supply `value`, and drop `defaultValue` on controlled inputs: React ignores it

Validation prompt

Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.

Rule walks component bodies for <input>, <textarea>, and <select> with a value attribute, then reports three shapes: (1) value with neither onChange nor readOnly, (2) value AND defaultValue together, or (3) value={state} where state was initialized as useState() with no argument or useState(undefined). The rule bails when any {...spread} attribute is present, so react-hook-form, Radix, and Headless UI are safe.

Evidence boundary

The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.

Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.

Record one outcome:

• Confirmed failure: The required evidence establishes the violation.
• Rejected: A documented exception or false-positive predicate applies.
• Needs evidence: Named evidence can still be collected.
• Unavailable: Required evidence cannot be collected in this run.
• Waived with evidence: An authorized, scoped exception applies to an established failure.
• Observation: The review records an optional tradeoff without claiming a defect.

A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.

Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.

Fix prompt

Apply this candidate correction only after the required evidence confirms the risk.

Initialize useState with a concrete value (useState(''), useState(false)) and pair value with onChange (controlled) or readOnly (intentionally non-editable). Drop defaultValue when value is also set: React ignores it on controlled inputs. Use checked rather than value for checkboxes and radios.
